A convergent boundary occurs when two tectonic plates move towards each other. This can result in one plate sinking under the other, or the two plates colliding to push the lithosphere upwards. What is formed from convergent boundaries? The geological features that are formed at convergent plate ...

convergent plate boundary processes. Our results provide direct evidence for lateral plate motions in the late Neoarchean, and arguably the operation of plate tectonics, albeit with warmer than average Phanerozoic subduction geotherms. Further, we surmise that plate tectonic processes played an important...
United States (Cascadia), and the northern Pacific margin of Colombia, where the direction of convergence is oblique; in these cases, as well as convergence between the two plates in the direction orthogonal to the plate boundary, there is a component of motion parallel to the plate boundary....
These features portray the crustal orogenic cycle and are first-order indicators of the thermal and mechanical evolution of the crust within the plate boundary region. This evolution is controlled by complex interactions among (i) the dynamic balance among forces that arise from plate-tectonic, ...
When oceanic plates collide with continental plates, the denser oceanic plate is forced under the lighter continental plate. This process has three geological results. The continental plate is lifted upwards, creating mountains. As the oceanic plate subducts, a trench is formed. Finally, as the de...
The presence of an inherited block of weak crust enhances the orogen-parallel drainage by imposition of localised subsidence zones elongated along a plate boundary. Evolution and reorientation of orogen-parallel drainage can sever links between gold placer deposits and their syn-orogenic sources. Many ...
